Here's the thing nobody gets. This is not an issue about blocking spam. What's at issue here is the ability of a privately owned business to provide whatever service or feature they want to for it's cutomers.

If people want to get E-mail from 360, they can call the ISP and complain, they can switch providers, or they can use an alternatvie service. None of which require courts threatening people at gunpoint.

Why does the US seem to think it rules the world and can tell everyone what's acceptable behavior?
